IMPROVEMENT IN ATTACHMENTS FOR WASH-BOILERS.

Specification forming part of Letters Patent No. 137,492, dated April 1,1873; application file-d February 17, 1873.

To all whom it may concern:

Beit known that I, THOMAS SHUMAN, of Corning, in the county of Adams andState of Iowa, have invented an Attachment for Wash-Boilers, of whichthe following is a specification:

The object of my invention is to provide a simple and cheap device to beused in a washboiler to aid in the circulation of water and steam, forthe purpose of washing clothing. It consists in forming a conductor, ofconoidal form, complete in one piece, with a series of openings near itsbase, and an open top and bottom, designed and adapted to be placed andoperated in a wash-boiler, in the manner hereinafter fully set forth.

My drawing is a perspective view illustratin g the construction of myinvention. It is composed of four separate pieces of sheettin joinedtogether to make one complete piece. It may, however, be cast completein one piece, and galvanized to prevent corrosion.

A A represent the sides. When made of sheet-tin they are of square oroblong form, and of equal size and form. B B are the end pieces, oftriangular form, alike in size and shape, and corresponding indimensions with the side pieces A A. The dotted lines indicate the seamswhere the pieces are joined together in a common way. The complete piecewill be round at the ends, and spread at the bottom so that it will havea wide base upon which to stand erect in the center of a boiler. Whenboilers have their bottoms depressed in the center my attachment can beset in the sunken part. When the boiler-bottom is flat and even theattachment is placed in the center, and will perform its functionequally well as when the boiler-bottom is depressed.

I 2 3 4 is a series of perforations. The size, form, and number of theholes may vary; but they must be near the lower edge.

To operate my attachment, simply place it in the center of a boiler, andput the articles to be washed around the attachment. This may be donebefore the soap-suds is put in, and before placing it over the fire; orit may be done after the boiler is over the fire, and the water or soapsuds boiling. The garments should be soaked, and the parts most soiledrubbed with soap before placing them in the boiler. When thns'properlyput over the fire the water will speedily boil within the conductorattachment, and rise therein until it overflows at the top, all around,and over all the clothing. The boiler should be covered to retain thesteam, which will condense at the top and unite with the current ofwater that overflows the articles, and percolates through them to thebottom, where it will again enter the conductor through the series ofperforations 1 2 3 4. A continued circulation of water and steam is thusproduced.

I am aware that conductors have been attached to the centers of devicesof various forms, and placedin boilers to accomplish the same resultscontemplated by my invention.

Claim.

I claim as my invention- The device A AB B, of conoidal form, completein one piece, with a series of perforations, 1 2 3 4, near its base,substantially as described and for the purposes specified.

THOMAS SHUMAN.
